I have been fighting with my BrightSign XD1230 to display an HTML5 URL with a calendar of events that scrolls up automatically using the CSS3 animate keyframe feature. When I do not include the "GPU Acceleration" code:
-webkit-transform: translate3d(0, 0, 0);
the text scroll is visibly jerky / choppy / jittery. When I include the GPU acceleration, the scrolling text is smooth, but it gets cut off at what appears to be the limit of the vertical resolution of my BrightSign player outputting over VGA (I have a single zone set to 1224 x 729, with offset of x 68 and y 19) . I have tried successive Firmware and BrightAuthor verisons, and am currently running what I believe is the latest Beta for both (BA 4.0.0.11 and FW 5.1.24).Any help or suggestions would be appreciated.
I have attached a sample html file that should demonstrate the issue.
Update: This is also a problem on the XD230, and on HDMI out as well as VGA.
